A lUNITED ST'IES PATENT Grrrcmf CHARLES GILMORE, OF INDIANAPOLIS,INDIANA.

GAS-MAKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 514,185, dated February6, 1894.

Application filed May 12,1893.

To @ZZ whom tm/wy concer/'141:

Be it known that I, CHARLES C. GILMORF., a citizen of the UnitedAStates, residing at Indianapolis, in the county of Marion and State ofIndiana, have invented a new and useful Improvement in Gas-MakingApparatus, of which the following is a specification.

My invention relates to an improvement in an apparatus for making a xedgas from crude oil. Y

The objects of my invention are first; to provide means whereby theoperation of the process may become continuous, second; to provide meansfor utilizing the heat generated to the greatest possible advantage.

The following drawings illustrate my invention. I

Figure 1 is a plan of the Whole plant. Fig.

. 2 is au end elevation wit-h the converting chamber shown in section.Fig. 3 is a side elevation of the converting chamber together with theusual seal, washer, &c. Fig. 4 is a longitudinal section of the boilersetting, looking downward, at the line 0.- Fig. 2. Fig. 5 is a verticalsection at the line Y- Fig. 4. Fig. 6 is a section of the converterchamber at the line -X- Fig. 2. Fig. 7 is a section of a form of oilburner which may be used in my apparatus.

In the drawings, A, indicates the boiler setting in which are mounteddistilling retort, B, and water boiler, C. Running longitudinallybeneath the retort B and boiler C respectively are passages, D, and, E,which are connected at their forward ends by the fire box, F, and attheir rear ends by the smoke box G, which communicates with a smokestack or chimney not shown. Running parallel with and between thepassages D andE is the passage, H, which connects the fire box F andsmoke box G. Mounted at the rear ends of the passages D, E, and H,respectively are the dampers, I, K, and L, so arranged that the draftthrough each passage may be regulated separately and at will. Passage,M, connects the pipes 2l and 22 leading from the converter, O, with thefire box F. Heat may be supplied to the boilers by means of the oilburners, N, or in some other well known manner. Y

O, indicates the converting chamber which is located in close proximityto the oil retort Serial No. 473, 907. (No model.)

B and is connected to the dome thereof by means of the pipe, P.Converter O is lined with fire-brick and is divided into two separatecompartments by means of the wall, R. Each of these two compartments issubdivided bythe walls, S, which extend to within a short distance ofthe top of the chamber. The converter is thus subdivided into fourcompartments, l, 2, 3, 4, which are filled with 'a fire-brickchecker-work. Chambers 1 and 2 communicate over the top of yWall S andchambers 3 and 4 communicate in a like manner, but the two sets have nocommunication with each other, the purpose being to utilize the heatabsorbed by the wall R, when the compartments 1 and 2/are in operation,in heating compartments 3 and 4 and vice versa. At the bottoms ofchambers 1 and 3 respectively are introduced the air-blast tubes, 5,and, 6, which are connected with any suitable blast producer and areprovided respectively7 with valves, 30, and, 31. Immediately above saidair tubes are respectively oil burners,7, and, 8, connected by pipes, 9,9, to a suitable oil supply, as tank, 37, andA by pipes, 10, 10, to thedome of the steam boiler. Between the burners and the oil supply areintroduced valves, 11, 12, 13, and, 14, andv between said burners andthe steam supply are the valves,

15, 16, 17, and, 18. Leading from pipe re-v spectively to the bottom ofchambers 1 and 3, immediately above the burners in said chambers are thepipes, 19, and, 20, provided with valves, 32, and, 33. Leadingrespectively from the bottom of chambers 2 and 4, to the passage M, arethe pipes, 21, and, 22, which are provided respectively with valves,`23, and, 24. Pipes, 25, and, 26, also emanate respectively from thebottom of chambers 2 and 4 and, through valves, 27, and, 28, areconnected with pipe, 29, which leads to the usual seal, washer, andreceiver used in gas-making plants. An arrangement (not shown) may beprovided whereby all of the valves in the system may be operated by asingle motion, the arrangement being such that when valves 11, 13, 15,17, 23, 30, 28, and 33 are open, valves 12, 14, 16, 18, 24, 27, 3l, and32 will be closed. Introduced respectively into the upper por-v tion ofchambers land 3 are pipes, 34, and, 35, which are connected throughsuitable valves, with the oil-supply, the arrangement IOO being suchthat if the gas generated in the converter is lackingin carbon a streamof oil may be introduced into the converter.

It will be understood that for the further supply of hydrogen, the usualsteam-jet may also be introduced into the converter.

The operation of my device is as follows;- A re being started in thelire-box F, dampers I and L are shut and damper K is opened thus causingall of the heat to traverse passage E. Steam having been raised in theboiler C and all of the valves being closed, damper I is opened, theheat is allowed to pass through passage D and under retort B and the oilis thus boiled and the vapor allowed to pass into the pipe P. Oil-valves11, 13, 12, 14; steam-valves 15, 17, 1G, 18; blastvalves 30, 31; andvalves 23 and 24 are then opened and the oil and steam issuing from theburners 7 andS are ignited. The heated gases from said burners pass upthrough chambers 1 and 3, down through chambers 2 and 4 and from thencethrough pipes 21 and 22 and passage M to the tire box F, thus utilizingthe hot Waste gases from the converter for the purpose of heating theboilers. When the checker-Work in chambers 1, 2, and 3, 4 have becomeheated to a white heat valves 11, 13, 15, 17, 30, and 23 are closed andvalves 32 and 27 are opened. The vapor of oil from the retort B isadmitted through valve 32 into the bottom of chamber 1 and is compelledto pass through the white-hot checker-work up through chamber 1, downthrough chamber 2, the vapor being converted during the passage into afixed gas, and the gas from thence passes through pipe 29, the seal andotherconnected apparatus to a gasometer (not shown). Vhen thechecker-Work in chambers 1 and 2 has become cooled nearly to the pointWhere no more fixed gas would be formed, valves 11, 13, 15, 17, 23, 28,30 and 33, are opened and valves 12, 14, 16, 18, 24, 27, 31 and 32, areclosed. By this means the oil vapor from retort B is cut off fromchambers 1 and 2 and is compelled to pass into and through chambers 3and 4 and from thence through the seal, While at the same time oil andsteam are supplied to the burners 7 the mixture being ignited by thestill incandescent bricks in chamber 1 and the chambers 1 and 2 areagain heated up. Vhen chambers 3 and 4 become cooled the process isagain reversed and so on ad injm'tum. As the process progresses t-heboiling point of the oil in retort B rises higher and higher. To providethe necessary heat therefor damper K is gradually closed until justenough heat is allowed to pass through passage E to supply the steamnecessary. If too much heat is being supplied to the boilers damper L isopened and the surplus allowed t-o pass up the chimney. When the lighterproducts from the oil in retort B have passed over the heavy residue isrcmoved and a fresh supply of oil is'introduced.

I claim as my invention- 1. In a gas-making apparatus, the combinationof the oil retort and the steam boiler ar ranged in a setting common toboth, the furnace arranged at one end of said setting, the Hue extendingbeneath theoil retort, the flue extending beneath the steam boiler, andthe central flue arranged between said flues, said fines being connectedWith the furnace and thereby with each other, and provided with dam perswhereby the products of combustion from the furnace may be directedbeneath either the oil retort or the steam boiler or both or directedtherefrom through the central flue all substantially as set forth.

2. In a gas-making apparatus, the converter consisting of a chamberhaving the partition wall R dividing the chamber into two separateindependent compartments, and the partition walls, S, S, located in eachof the separate compartments, arranged at right angles to said partitionwall R, and extending nearly to the top thereof, thus forming thecommunicating sub-divisions 1 and 2, and the communicating sub-divisions3 and 4, and means for introducing fuel and gaseous elements into theseparate compartments, whereby the heat from one sot ot saidcommunicating subdivisions is imparted to the other set of communicatingsub-divisions, all arranged substantially as and for the purpose setforth.
